So last night I found a car I loved at a great price, but the dealer wasn't really willing to haggle on the amount they'd give me for my trade-in. I ended up walking away from the deal to see if anyone else would give me a better trade-in. As it turns out, that answer was no by about $4000. I want to go back to the original dealer tomorrow. My question is, should I tell them I was there on Thursday and I want the same deal/price they offered then, or should I roll the dice and see if they offer me something better?

:::EDIT::: I was being an ass about the whole thing - I can admit that. I spoke to the sales guy who helped me last night and he agreed to honor the deal he offered last night. I'm getting the car after work.
